To all @li/mm 'it ymay concern.:

Be it known that l', HENRY F; LOEWER., a citizen ol' the lllliled States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful `Improvements in Lasls,oiz which the following is a speeilicatiim.

lhis invention relates to the class of lasts in hieh a heel bloc-k is movable Withrefelence io the toe part, in order to shorten the last and permit the removal of the shoe therefrom, and further to that elass ot lasts in which an instep portion is collapsed with reference to the remainder of the toe art, in order io facilitate movement of the s ioe.

In the drawings Figure 1 is a longitudinal section of a 'fast embodying this invention, the parts being in the position of complei e expansion. Fig. 2 is a like longitudinal section, the parts being in the position of the greatest reduction; and Fig, 3 is a cross- 'seelion on the line 3-3 of Fig. 1.

` 'lhe heel block 1 contains a thimble 2 having upon it a worin 3, and held in place in the heel block by a cross pin 4. The thimble 2 is irregularly shaped on the inside in order are separated by a flat division line or sur`4 to iit n on a jaek post 5 of similar shape, so that said jack post may operate as a ke to turn the thimble 2 and Worm 3. The eel block is slotted, as at 6', to hold the hingeor eonneetor between the two parts of the last, and is also perforated, as at 7, in order to take the thimble 2 and the larger Worm 3 and to hold them in position in the heel block. The slot 6 intersects the cavity cr perforation 7, at least at the point adjacent to the worm 3. The two parts of the last are held together by means of `a plate 8, which is" pivotfe'd in the vertical slot 6 by means of a cross pin or pivot 9, and said plate hasa series of teeth 10 cut-upon it to form a segmental ear upon a circle drawn from the center o the pivot 9. The teeth 10 mesh with the threads of the Worm 3, as shown. The heel block and .the toe part ofthe last face 11 ,V Which is diagonal with reference to a horizontal plane and to a vertical plane passing throughthe axis of the thmble 2, so

that When the toe part l2 of the last is raised, as shown in Fig. 2, from the position shown in Fig. 1, the toe part Will move along said diagonal shortening of t e total last and a relief of the heel of the shoe that Will permit the Withdrawalof the shoe from the last. Thus, oi

tion 19 is co lane 11 so as to vproduce aV positions are shifted siinultaneously both longitudinally and transversely, in the diagonal movement along the plane 11. 'lhe ond of the plate S rests in a vertical slot 13 in the toe part 12, and is held in place by two pins 15 and 17, whose ends are 'fastened in the too part l2 and pass through slots'lG and 1S in the plate 8. 'lhe slot 1S is between the slot 16 and the pivot pin S. 'lhe slot 16 is eut on a line intersecting the pin 15 and the pin 0, and the slot 1S is drawn on a circle having the pin 15 as its center, and has sueh a length that theends of the slot 13 l'orni stops for the movement of the pin 1 7 and determine the two extreme positions of the last shown in Figs. 1 and 2. The slot 18 guides the toe part 12 of the last so as to keep the surfaces of the toe part and of the heel block on the line or plane 11 in Contact With each other as the plate 8 swings around its center or pivot pin 9. At the saine time the pin 15 moves slightly to and from the pivot 9 in thev movement of the toe part, shown in Figs. 1 and 2.

It will now be seen that if the parts are in the position shown inFig.- 1, and the last is turned with reference to the ack post 5, the plate 8 will be turned upon the Worm 3 and this movement will cause the plate 8 tol tilt on its pivot pini), which will lead theouter end of the plate S and the toe part 12 to the position shown in Fig. 2; and if the last is turned back with reference to the thim'ble 2, the parts .will be returned to the position in Fior. l. l

1t is evident that a key may be used in place of the jack post 5, and that said jack post merely constitutes a convenient key for producing the movement just' described.

The toe part 12 of the last may have a transverse slot 14 severing 'the instep portion' 19 from the remainder oi the toe part.v This slot 14 has a suitable Width When open, as shown in Fig. 1, so that When the inste porlapsed toward oragainst t e remainder of the toe part 12, as for instance into the position shown in Fig. 2, the size of the last across the instep Will'he suiiiciently reduced to permitthe easy'removal of the.

shoe therefrom. inthe drawing, the instep .portion 19 remains' integral with the remainder of the toe portion 12, but, of course, may be hinged thereto in any suitable manner. In order to collapse and expand the instep portion 19, the plate Suis provided With va slot 21 in which runs a pin 20 fixed in the Y instep 'i shape lt at the instep portion 19 separates from the remainder of the toe part 12 when `ortion 19. The slot 21 is of such the upper surface of the heel block 1 matches the remainder of the bottom ofthe last as shown in Figtlybut said instep portion 19 i v is collapsed or drawn to the remainderof the toe art 12, as shown in Fig. 2, when the heel bloclli 1 is lowered from the ositionjiist describ'ed. The o eration of t is instep device is as followszpon turning the last with lreference to the Jack post 5, thef'plate 8 is rocked on the pivot pin 9 by its engagement with the wQrm 3, so that the slot 21 actuates the pin to collapse the last and block 19 toward or against the remainder ofthe toe part 12, the pin 15in the 'slot 1'6 taking the pressure.V Turning the last in the opposite 'direction replaces the parts from' the position shown 1n Fig. 2 to that shown in Fig. 1.
